Compact Step-Up Modules for DIY Power

This pack contains twenty mini boost modules that raise a single-cell lithium battery to 5 V, 8 V, 9 V or 12 V. They suit hobbyists and prototype builders who need a tiny, adjustable DC-DC board for low-power projects.

Input Range and Current Limits

Each board accepts 2.5 V up to 0.5 V below the chosen output and is rated for a maximum of 1.5 A combined input and output current. The default 12 V setting draws about 6 mA for the on-board LED indicator, which can be disabled to save that overhead.

Output Capability and Voltage Selection

With a 3.7 V lithium cell the modules deliver 5 V at 1 A, 8 V at 0.7 A, 9 V at 0.6 A and 12 V at 0.5 A. Output voltage is set by bridging two solder pads labelled A and B on the 22 mm by 11 mm PCB, giving four fixed levels without extra components.

Questions about this item

Which output voltage should I select for my project?

The module can be set to 5V, 8V, 9V or 12V by bridging pads A and B on the PCB; 12V is the default setting.

What current can I draw from a 3.7V lithium cell at each voltage?

With a 3.7V input the board delivers up to 1A at 5V, 0.7A at 8V, 0.6A at 9V and 0.5A at 12V, provided neither input nor output current exceeds 1.5A.

What input voltage range does the boost converter accept?

The input must stay between 2.5V and 0.5V below the chosen output voltage, so a single-cell lithium battery works across all four output settings.
